mcp_git_commit_files · Local Code MCP: Risk & Policy

WHAT IT DOES

What mcp_git_commit_files does on Local Code

AI agents use mcp_git_commit_files to create or update resources in Local Code — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Local Code environment.

WHY IT NEEDS A POLICY

Why mcp_git_commit_files needs a policy

The tool creates git commits, which are write operations that modify the repository state. While commits are technically reversible through git operations (revert, reset, amend), they do create permanent entries in the history and can affect multiple developers' views of the codebase.

From the tool's definition Tool description states 'create one git commit' which modifies the repository history by staging files and committing them. This is a reversible write operation (commits can be reverted via git revert or reset).
